Print Recipe

These make-ahead turkey avocado croissant sandwiches are the perfect solution for busy days. Layered with creamy avocado, savory turkey, and provolone cheese on a buttery croissant, they taste even better after sitting overnight.

Ingredients

Scale
  • 4 large croissants (day-old works best)
  • 1 pound sliced turkey breast (oven-roasted from deli counter)
  • 2 ripe avocados (Haas recommended)
  • 1 tablespoon fresh lemon juice
  • Salt and black pepper (to taste, about 1/4 teaspoon each)
  • 4 slices provolone cheese (or Swiss)
  • 2 tablespoons Dijon mustard
  • 1 cup fresh spinach leaves (optional)
  • 1/4 cup mayonnaise (full-fat recommended)
  • 1/2 red onion, thinly sliced (soaked in cold water for 5 minutes)

Instructions

  1. Prepare the avocado spread: Cut avocados in half, remove pits, scoop flesh into a small bowl. Add lemon juice, salt, and pepper. Mash with a fork until smooth but slightly chunky. Taste and adjust seasoning. Set aside.
  2. Slice the croissants: Using a serrated knife, slice each croissant horizontally through the middle, leaving one side attached if possible.
  3. Spread the base: On the bottom half of each croissant, spread about 1 tablespoon of mayonnaise. On the top half, spread about 1/2 tablespoon of Dijon mustard.
  4. Layer the turkey: Fold turkey slices and layer evenly on the bottom half of each croissant (about 4 ounces per sandwich).
  5. Add the cheese: Place one slice of provolone on top of the turkey on each sandwich.
  6. Spread the avocado: Divide the avocado mixture evenly among the four sandwiches, spreading it on top of the cheese.
  7. Add the toppings: Layer fresh spinach leaves and sliced red onion on top of the avocado.
  8. Close and wrap: Gently press the top half of the croissant onto the fillings. Wrap each sandwich tightly in plastic wrap or wax paper.
  9. Refrigerate: Place wrapped sandwiches in the refrigerator for at least 2 hours, or overnight.
  10. Serve: Enjoy cold straight from the fridge, or warm in a 350°F oven for 5 to 7 minutes (unwrap first if warming).

Notes

For best results, use day-old croissants as they hold up better. The lemon juice in the avocado spread helps prevent browning. Wrap sandwiches tightly to exclude air. For a warm sandwich, toast in a 350°F oven for 5 minutes; avoid microwaving as it makes the croissant soggy. Sandwiches keep in the refrigerator for up to 2 days or freeze for up to 1 month.
